Experience More Freedom with a Second or Spare Battery

Maximize the productivity you get from laptop mobility. Adding a second battery to your Dell^TM  laptop - or keeping a charged spare battery on hand - can help:

Adding a battery to a laptop expansion bay (optical drive bay) may double your run time between charges. Work longer without worrying about finding an electrical outlet to charge up. No available expansion bay? Keep a spare charged battery with you and continue working when your primary battery is discharged, no matter where you are. Enjoy more wireless freedom. You can't take full advantage of wireless networking if you have to plug your laptop's AC adapter into a wall outlet; yet wireless networking can discharge your battery faster. A second or spare laptop battery is the answer. If you use your laptop to watch DVDs, you've probably noticed it reduces battery run time. A second or spare battery can help make sure you see the final credits.
